Where are the 220 Swift gone?

Checking all major rifle producer catalogues I have seen, nobody produce a varmint rifle in that old chambering I love so much.
In the past I had a Ruger MKII Varmint in 220 Swift I sold to buy a Rem Varmint in the same caliber, but as soon as I went to the gun shop, no more Swift have been available.
It is now at least a couple of year I try to find it again. No Rugers, no Remingtons, no Savages.
Why?

I hope they don't quit making the brass because my best 22 cal is the 220 weatherby rocket which is all you can get out of a 220 swift case. Roys first wildcat and amazing. 52 grain nosler match bullets at 4100 fps. Ravens hate me when I use it because prarie dogs vaporize on impact and not many scraps. Costs me a few dogs to since there is no body to attract more of the little cannibals out to feast.

I have an old Ruger #1 in 220 Swift. It's ok but no special properties. What would a fast twist barreled 220 Swift offer? It could shoot heavier but slower bullets allowing a little longer supersonic range, but you can easily get longer range with less barrel wear with larger bores and VLD bullets. 6.5 or 7mm in several good cartridges).
